Tuple DIP

[Timothee Cour]

the DIP says this replace std.typecons.TypeTuple however no mention is
made of named arguments, so I don't see how they could be a
replacement (nor how would that allow for a migration path) without
mentioning a word on this, eg:

what would be the equivalent of this ?
` writeln(tuple!("x", "y", "z")(2, 3, 4).y); `
